they S A Y Gilgalad because his name IS Gilgalad but for the construction of the name Tolkien used the words gil+calad which together makes gilgalad - in Sindarin, the consonants at the beginning of a word change when put together with an other word
so together with gil it makes c -> g
but together with an it makes c -> ch because n is a nasal and L is a liquid which causes soft mutation instead of nasal mutation 😉 depends on the word not on the speaker
Birthday would be "Nostrad" or "Nostor" in Sindarin, in Quenya "Nosta".
